Undergraduate Thesis

Making Android Apps Safer: Improving the Portability of Tools that Monitor In-App Behaviour

Advisor: Diomidis Spinellis & Nikolaos Alexopoulos Year: 2025

This thesis addresses the portability challenges of kernel-level tracing in diverse Android devices, emphasising behavioural reconstruction via the SliceDroid approach. Practical contributions include an improved tracing setup and stream- lined device-specific configurations.

Research Interests

I enjoy working across the stack, from data collection and modelling to deployment and evaluation, with a focus on real-world impact and reliable software.
